PURPOSE: To systematically review the literature about maternal and neonatal outcomes following induction of labor (IOL) and spontaneous labor (SL) in women with previous cesarean section (PCS).
METHODS: PubMed, Medline, EMBASE, Cochrane library searches; January 2000-February 2013.
INCLUSION CRITERIA: women attempting labor after PCS, singleton term pregnancies. Women undergoing IOL were compared with women in SL. Method for induction, mode of delivery, uterine rupture/dehiscence, post-partum hemorrhage, emergency hysterectomy and any maternal or neonatal morbidity and mortality were analyzed. MOOSE guidelines were followed. Interstudies heterogeneity was tested. A random effect model was generated if heterogeneity was >25 %. Pooled odds ratio with 95 % confidence interval (OR, 95 % CI) were calculated.
RESULTS: Eight articles included 4,038 women with IOL (23.2 %) and 13,374 women with SL (76.8 %). IOL was associated with a lower incidence of vaginal delivery (OR 0.66; 95 % CI 0.55-0.80) and higher rates of cesarean section (OR 1.52; 95 % CI 1.26-1.83), uterine rupture/dehiscence (OR 1.62; 95 % CI 1.13-2.31), and post-partum hemorrhage (OR 1.57; 95 % CI 1.20-2.04), although hysterectomy was similar between the two groups (OR 2.60; 95 % CI 0.52-13.1). Neonatal morbidity was similar after IOL or SL (OR 1.13; 95 % CI 0.75-1.69).
CONCLUSIONS: Induction of labor increases the risk of uterine rupture/dehiscence and of repeat cesarean section.
